Chassis Electrical Systems
Slaběňák, Patrik ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Travelling by bus is very extended in present and safety return home is a wish of every passenger. Outcome of this bachelor work is a survey of the most used stability systems, used in cars and facilitating the work of drivers in critic situations. Among others, this work contains the survey of powers acting on a vehicle during the ride. This powers influence impending slippery road on aggravated adhesive conditions. Individual systems are described attentively and supplemented by illustrating pictures, which near this issue and facilitate the real idea of functionality. At the conclusion of this work is mentioned the theoretical suggestion for practical exercising of a subject automobile electrotechnics and also a referring is mentioned to my continuation in this dissertation.

Design of intelligent wiring Foxtrot for multipurpose building
Račuch, Marek ; Tesař, Radek (referee) ; Bátora, Branislav (advisor)
The present bachelor thesis is concerned with system wiring. Possible applications, various types of bus systems and wiring topology are discussed in the paper. The thesis is structured into three main sections. Section 2 elaborates on the capabilities, structure and topology of system electro installation and the third section discusses a system electro installation Foxtrot in particular, describing individual components with an overview of basic modules for utilization in residential buildings. The overall structure of system wiring is described along with a brief description of basic system components of Tecomat Foxtrot from Teco a.s. company suitable for home installation. Section 4 focuses on description of the designed object and for the proposal of the whole project of system wiring using the elements of the Foxtrot system for multipurpose building.

Control unit for positioning control of the experimental positional table
Fries, Lukáš ; Řezníček, Michal (referee) ; Adámek, Martin (advisor)
The work is devoted to the theoretical characteristics of the used components and its functioning. The main part is focused on practical design and build a functional device for control the position of the table, which is part of some unspecified workplace. Attention is mainly concentrated on the ATmega328, which is part of the module Arduino for control sub systems. The document describes a closer communication with the computer, which can be selected as a control element positioning apparatus. Change of position is provided by two stepper motors. The primary control was designed using buttons and the position information is the operator transmitted to the display. The whole concept is subject to the requirements on the reliability and accuracy with an emphasis on simple operation.

Control unit for garden pool
Jansa, Josef ; Matěj,, Zdeněk (referee) ; Mego, Roman (advisor)
This work deals with the regulation of the water temperature in a small garden pool. The practical part consists of practical design control unit garden pool which is based on knowledge of the ambient air temperature and the temperature of the solar panel, evaluates and controls the filtration pump bypass valve and solar panel. Temperature sensing is done using digital sensors DS18B20 more 1-Wire bus. The control unit is formed by 2x4 matrix keyboard keys. All data are displayed on the alphanumeric display 2x16 characters. Control element is a microcontroller Atmel ATmega 3250PA. Furthermore, discussed in this thesis is data transfer using Bluetooth module.

Data diagnostics in modern car control units
Hájek, Ondřej ; Vítek, Richard (referee) ; Prokeš, Aleš (advisor)
Presented Diploma thesis is aimed on design and implementation of car diagnostic interface of engine control units EDC. Diagnostic interface provide communication between car and computer by USB interface. User will be able to task commands by developed computer application. For developing application is necessary to get information about used protocols and basic knowledge in car’s hardware. Understanding OBD2 standard and communication protocol CAN, eventually KWP is necessary for design the solution. Main purpose of this thesis is to store enough usable information about car diagnostic for future continuation.

Engine Motormanagement Software
Kuda, Roman ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Increasing requirements and claims on running of motor vehicles contributed to development of new systems on the mixture preparations of fuel and ignition. Cardinal causes, which led to the very intensive research and later introduction of superior systems of injection and ignition, where fulfilment of stricter emission limits, lower fuel consumption at prezent engine-power increase and engine torque. The conception of the classical gas-engine was not changed over the past few years. The supervising elements as ignition and injestions of engines are continuously changed.

Possibility of Measurement Automation
Ilichman, Ondřej ; Košíková, Jana (referee) ; Vdoleček, František (advisor)
The thesis is focused on the automation of measurement with the using of hardware and software. Efforts to objectification processes and eliminating human influence on the outcome are increasingly reflected in the technical fields of measurement. In this work, methods of measurement modification, transformation and subsequent analysis of the measured quantity are discussed. Since nowadays it is possible to automate nearly all types of measurement, it is shown, under what circumstances is appropriate to use automated measurements. The final section is devoted to solution of software and hardware design for measuring temperature in the server room. They are proposed 3 possible solutions and on the basis of their analysis the optimal variant is chosen.

Control unit for CubeSat
Horký, Jan ; Šulc, Tomáš (referee) ; Kubíček, Michal (advisor)
Cílem práce je návrh univerzální řídicí jednotky pro CubeSat založené na obvodu FPGA. Taková jednotka doposud nebyla komerčně dostupná a navržená jednotka má tak dobrý potenciál zaplnit příslušné místo na trhu komponent pro CubeSat. Celá jednotka je navržena z komerčně dostupných komponent. Návrh jednotky je proveden tak, aby umožnil její funkci ve vesmírném prostředí. Stav konfigurace FPGA je pravidelně kontrolován a v případě zjištěné chyby dochází automaticky k rekonfiguraci FPGA a návratu jednotky do výchozího stavu. Jednotka obsahuje sadu senzorů, které monitorují její stav a v případě potřeby je možné na základě jejich výstupů provést opatření z hlediska ochrany funkce jednotky. Dvě paměti MRAM umožňují uložení tovární a uživatelské konfigurace FPGA, mezi kterými dochází k automatickému přepnutí na základě korektnosti uživatelské konfigurace.
